This study assesses how banking sector integration and especially cross-border lending affect macroeconomic stability. I use a two-country general equilibrium model with heterogeneous banks that are hit by idiosyncratic shocks. According to the concept of granularity, idiosyncratic shocks to...

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank...

The German economy has veered back on an upward course, after weak growth in the summer semester 2014. In this projection, real GDP is estimated to grow by 1.5 percent in 2014, by 1.4 percent in 2015 and by 1.7 percent in 2016. Inflation is projected to remain low, with 0.9 percent in 2014, 0.7...

The German economy continues to recover, and will grow by 2.2 percent in 2015. With slightly abated increases, the annual growth rate will be 1.9 percent in 2016. Driven by this favorable economic development, the unemployment rate will further decline, to 6.4 percent this year and 6.1 percent...

Das DIW Berlin prognostiziert für die deutsche Wirtschaft für 2011 ein Wachstum von 2,7 Prozent, im Jahr 2012 dürfte der Zuwachs noch 1,4 Prozent betragen. Besonders im ersten Vierteljahr 2011 dürfte bei der Wirtschaftsleistung ein deutliches Plus von knapp einem Prozent gegenüber dem...

Das DIW Berlin prognostiziert für die deutsche Wirtschaft im Jahr 2010 ein Wachstum von 3,4 Prozent, im Jahr 2011 werden es 2,0 Prozent sein. Der Aufschwung nach der schwersten Rezession der Nachkriegszeit verläuft damit kräftig, auch wenn die hohen Wachstumsraten der ersten Jahreshälfte...

We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...
